Ourhzif EM, Decombat C, Abrunhosa-Thomas I, Delort L, Khouili M, Akssira M, Caldefie-Chezet F, Chalard P, Troin Y. Synthesis and Biological Evaluation of New Naphthoquinones Derivatives. Curr Org Synth 2020; 17:224-229. [DOI: 10.2174/1570179417666200212111956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 01/17/2020] [Accepted: 01/20/2020] [Indexed: 01/31/2023]
Abstract
:
New substituted 1,4-naphthoquinones have been prepared in good overall yields through the
naphthol route. The cytotoxicity of these compounds was tested in vitro on MCF-7 breast tumor cells. The
most active compound 14 displayed an IC50 of 15μM.
Objective:
To investigate the cytotoxicity of new naphthoquinones derivatives on MCF-7 cells.
Methods:
Synthesis of new naphtoquinones derivatives and in vitro evaluation of their cytotoxicity on MCF-7
cells (rezasurin cell-based assay).
Results:
Starting from Ethyl 4-hydroxy-6,7-dimethoxy-2-naphthoate, four naphthoquinones were prepared and
exhibited substantial cytotoxicity against MCF-7 cells.
Conclusion:
Preliminary studies of the structure-activity relationship have shown the influence of the structural
parameters and, in particular, the nature of the naphthoquinone side chain.

Abstract
Alkoxyallenes are easily available and versatile building blocks for the preparation
of a variety of natural products (terpenes, polyketides, alkaloids, amino acids, carbohydrates
etc.) originating from different classes. The synthetic use of the three allene carbon
atoms frequently follows the “normal” reactivity pattern showing that alkoxyallenes
can be regarded as special enol ethers. Additions of alcohols or amines to alkoxyallenes
form vinyl-substituted O,O- or N,O-acetals that are frequently used in ring-closing
metathesis reactions. This methodology delivers crucial heterocyclic units of the target
compounds. Enantioselective additions provide products with high enantiopurity.
Alternatively, an “Umpolung” of reactivity of alkoxyallenes is achieved by lithiation at
C-1 and subsequent reaction with electrophiles, such as alkyl halides, carbonyl
compounds, imines or nitrones. High stereoselectivity of the addition step can be achieved by substrate control
or auxiliary control. The high diastereo- or enantioselectivity is transferred to the subsequent acyclic or cyclic
products. The cyclization of primary addition products occurs efficiently under mild conditions and provides
functionalized dihydrofuran, dihydropyrrole or 1,2-oxazine derivatives. These are valuable intermediates for
the synthesis of a variety of heterocyclic natural products. Nazarov cyclizations or gold catalyzed rearrangements
allow the synthesis of five- and six-membered carbocyclic compounds that are also used for natural
product synthesis.
Dedicated to Dr. Reinhold Zimmer, a pioneer of alkoxyallene chemistry, on the occasion of his 60th
birthday.
